Cequence Security Links AI Gateway to Zero Trust Focus on Agent Behavior

Cequence Security issued an update arguing that AI security efforts should focus on what AI agents do after they gain access. The company linked the shift to multiple published views and its own AI Gateway approach, framing agent behavior as the area that requires control rather than authentication alone.

In the company’s account, Anthropic’s frameworks, Dr. Chase Cunningham’s Agentic Zero Trust research, and Cequence’s AI Gateway architecture align on a shared emphasis: securing runtime behavior instead of relying on login controls. The stated concern focused on misuse of legitimate access to take harmful actions, manipulate APIs, or exfiltrate data.

Cequence described a behavior-focused model in which agent activity is intercepted, analyzed, and tightly controlled through policy enforcement and threat detection at each step of a transaction. The company also described behavioral monitoring and policy enforcement as dynamic and real-time, citing the ability for agents to chain legitimate steps into harmful patterns.

Cequence tied its approach to guidance in the Center for Internet Security’s Model Context Protocol (MCP) Companion Guide, published April 20, 2026, and said the guide frames MCP as a control point for governing AI agent behavior. The company stated that its AI Gateway operationalizes the guide through explicit tool-level permissions, auditable interactions, generation of least-privilege agent personas, logging every API call, and applying DLP scanning to tool requests and responses. “Most security teams are still trying to tackle AI risk with prompt detection and short-lived tokens – basically, really tight sign-in security. But that misses the point entirely. You can nail authentication and still get burned by an agent running amok inside the castle,” said Shreyans Mehta, CTO at Cequence Security. “Traditional security controls focus obsessively on the front gate – who gets in. But with AI agents, the real damage happens after the front gate, through totally authorized channels,” said Dr. Chase Cunningham. Forward-looking statements were not present in the provided text.
